About
Primula florindae (Si), the Tibetan cowslip, is a vigorous, deciduous herbaceous perennial with long-stalked, broadly ovate, green leaves. Clusters of scented, nodding, pale-yellow flowers appear from July to August. Thrives in slightly damper soil, beside streams and ponds � an outstanding and rewarding large primula for a cool, moist border.
